Abstract: In a gas sensing system, a light emitter can emit light through a gas sample toward a concave reflective surface. The reflective surface can redirect the emitted light to propagate through the gas sample toward a light sensor. Using, optionally, the Beer-Lambert Law, the system can determine a concentration of the gas material in the gas sample. By selecting a specified shape for the reflective surface, such as a complete or partial ellipsoid, and locating the light emitter and the light sensor in specified locations, such as at one or both foci of the ellipsoid, the gas sensing system can reduce variation in optical path length, from optical path to optical path, in the light that propagates from the light emitter, to the reflective surface, and to the light sensor. Reducing the variation in optical path length can improve an accuracy in determining the concentration of the gas material.

Abstract: The present invention relates to a portable digital reader for reading an analysis target chip including a plurality of test areas. The reader comprises: a light emitting section having light emitting elements for radiating light; an integral optical splitter for uniformly distributing the light from the light emitting section to each test area of the analysis target chip; a light receiving section for receiving light reflected from each test area so as to convert the same into electric signals; and a measuring section for measuring concentration according to the electric signals obtained from the light receiving section. Therefore, it is possible to prevent the generation of errors in signal measurement due to optical distribution failure by assembling branch sections of the optical splitter under the control of the number of the branch sections according to the number of test items in a test strip.

Abstract: A device and method for identifying solid and powdered materials use near-infrared reflection spectroscopy combined with multivariate calibration methods for analysis of the spectral data. Near-infrared reflection spectroscopy is employed within either the 700-1100 nm or the 900-1700 nm wavelength range to identify solid or powdered materials and determine whether they match specific known materials. Uses include identifying solid and powdered materials with a fast measurement cycle time of about 2 to 15 seconds and with a method that requires no sample preparation, as well as quantitative analysis to determine the concentration of one or more chemical components in a solid or powdered sample that consists of a mixture of components. A primary application involving identification analysis verification of the identify and purity of powdered materials used for fabricating drug tablets and capsules for quality control purposes.
